Thanks for your answers.
I am now the sub-maintainer of vfio-platform. I will handle the rebase of these serie and fix "[PATCH v3 0/6] vfio: type1: support for ARM SMMUS with VFIO_IOMMU_TYPE1". New versions are coming soon.
Regards,
Baptiste

For a start, it looks like the dependency mentioned below is still not
in, which is a bit of a problem.
Also, trying to merge your branch below (after fixing the URL), I get
some conflicts with the current mainline, so that's a bit of a show
stopper too.
Can you start by rebasing on top of 4.0-rc1 with all the dependencies,
reposting the series, and cc-ing the original author of the patches (as
I cannot see Antonios on the CC list)?
Thanks,
M.
